Application filed June 23, 1924.

To all whom it may concern:

Be it known that I, G ORGE T. SCOTT, a citizen of the United States, and a resident of Susanville, county of Lassen, State of California, have invented a new and useful Glass Cutter, of which the following is a specification.

This invention relates to glass cutters which are held in the hand and drawn across a sheet of glass to cut the same and it has particular reference to the type of glass cutter wherein a small beveled edge, hard steel wheel serves as the cutting tool, though it is also useful with the diamond pointed glass cutters.

The objects of my invention are to provide an improved body construction with a grip having a device adapted to go around the finger holding the instrument to prevent it swerving or twisting, also a handle which is adapted to receive new cutting wheels set in a special mounting, and also a more compact form of glass cutter than the present type.

I achieve these objects in the glass cutter shown in the accompanying drawings, and in which:

Figure 1 is a side elevation of my glass cutter shown in about the position it would occupy if in the act of cutting a sheet of glass. I Figure 2 is a view of Figure 1 from the line 22.

Figure 3 is an enlarged perspective view of the detachable wheel tip.

Figure 4 shows the lower part of the glass cutter as seen in Figure 2 but shows a wheel set permanently between the sides of the doubled over sheet forming the body.

Figure 5 is a perspective view illustrating my cutter in operation with the ring over the index finger of the operators hand.

In further detail my glass cutter comprises a body 1 preferably of sheet metal shaped into an elongated handle portion having a ring 2 hingedly gripped at the upper end by the metal of the handle being formed into an eye 3 about the ring.

The ring is limited in its swinging movement in the eye to the position 2 shown in Figure 1 by reason of two shoulders 4 on the handle which stop the ring, but it may be swung downwardly as indicated by the dotted position 2'.

At the lower end of the handle the metal is formed into a slightly concave seat 11 SeriaI No. 721,951.

for the end of the users finger and beyond this point the metal is folded upon itself to form a body as shown at 5 and is notched at the folded edge as at to form the jaws common to glass cutters. The lower end of the folded body is slotted at 6 to receive a detachable wheel carrier 7 to which is pivoted the cutting wheel 8. This carrier 7 is more clearly shown in the enlarged view of Figure 8 and consists of a piece of sheet metal bent into a U shape and with the wheel 8 rotatably mounted between the U sides on a rivet pin 9.

The portion of the folded body embraced by this U piece wheel carrier is reduced in thickness from the balance of the body so that when the carrier is in place its sides will be flush with the body sides and thus present an even surface to hold against a straight edge in cutting the glass, and the carrier and engaged portion of the body are also very slightly tapered so as to insure a tight sliding fit of the carrier over the body.

Th wheel carrier being U shaped also resiliently clamps to the body along the sides. Instead of the detachable wheel carrier, the folded side walls 5 of the body may be separated slightly if desired and the wheel pivoted between them as indicated in Figure 4.

Figure 5 shows my glass cutter being drawn along a rul 12 in the process of cutting a sheet of glass 13.

Ordinarily the rule would be placed against the near side of the cutter but is here shown on the far side so as not to hide any part of the device.

The ring 2 is shown embracing the index finger of the operators hand and with the end of th finger seated in the concavity 11 formed on the handle at its juncture with the body 5, and with the thumb gripping the handle just under the concavity.

From this drawing it will be seen that the ring overcomes any tendency of the cutter to twist or swerve from the straight path of travel, and the concavity on the handle for the reception of the end of the finger provides for a concentration of pressure on the cutting wheelboth features of considerable importance, especially in the cutting of odd shapes as in art glass work where frequently no rule or guide is used.

In the osition of use as shown the pressure on t e wheel keeps the wheel carrier forced tightly in place and the U shaped carrier passing through the slot in the bot y cannot be loosened by the dragging action of the roller.

Having thus described my invention and shown it as formed of sheet metal, it is of course apparent that it could be similarly shaped from east or other metal and my appended claims are intended to include any such obvious modifications as come within the spirit of the invention.

I claim:

1; A glass cutter of scribed having a finger the character deembracing portion on the handle.

2. A glass cutter ot the character described having;- a body with a cutting element thereon and a handle extending theretroin with a finejer encircling; element on the handle.

3. A glass cutter of the character described having a body with a cu ing element tnereon and a handle extending tl erefrom with a linger encircling ring mounted at the end of the handle.

4.11 glass cutter of the character described having a body with a cutting elenient thereon and a handle extending therefrom with a linger encircling ring hingedly mounted at theend of the handle.

A glass cutter of the character deed having a handle with a finger cinbrac ng portion thereon and a concave seat for the end of the pressure applying linger oi -the user.

6. A glass cutter of the character described having a handle and a body portion supporting a cutting element, said cutting element being mounted in a separable carrier adapted to itrictionally engage the end of the body. 1

7.- A glass cutter of the character described having a handle and a body portion vet-ting a cutting element, saidcutting l ment being a beveled edged wheel rota tacly mounted between-the sides of a U element being a beveled edged wheel shaped separable carrier adapted to frictionaliy engag the end of the body,and the body being slotted upwardly from its lower end for the reception of the connecting web carrier.
